To all 'whom t may concern.'

Be it known that I, CHARLES HAMMER, a citizen of the United' States, residin at Queens, in the county of Queens and of New York, have invented certain new and useful Improvements in Band Receptacle- Closures, of which the following is a speciiication.

This Iinventionrelates to closures for receptacles of the wide-mouthed variety, and is particularly adapted vto be secured on a receptacle provided with a flange on the outer wall below the top, around which the closure is secured.

The object of the present invention is to provide a closure for a wide-mouthed receptacle in which a separate member is provided to secure the top closin member in position on top of the receptac e, by en'- gagement with the flange on the receptacle; and which closure can be readily loosened for removal by merely pulling on a tongue' or extension of the sealing member.

-In the accompanying drawing showing one embodiment of my invention, Figure 1 shows the closure in sealing posltion on a receptacle. Figs. 2 and 3 show'the principal members of the closure, and Fig. 4 the gasket for the same. Fig. 5shows the receptacle on which the closure is sealed in Fig. 1. Fig. 6 is a fra entarv view in sec rlslt applied, and Fig. 7 is asimilar view with the parts in sealing position; and'Fig. 8, shows in section the closure sealed on another form of receptacle.

' The closure as shown comprises essentially` two members, a cap member 10, shown in Fig. 3, and a ring or band member 11,

shown separately in Fig.` 2. The cap memthat forms a kind of bead on top ofthe cap,

bercomprises a flat disk 12 lhaving a comparatively short liange 13 projecting downwardly of cylindrical form. Preferably the disk connects with the cap by a comparaand provides a shallow channel inside of the ca that will coperate with a gasket 15. T e latter is shown of ringjform, of a ize to be inserted in the acap, as shown in ig. 6.

The band or ring member 1'1 is .in the l form of a flat band that is wider than the flange portion 13 of the cap, and is pro# vided with an inwardly extending flange 16` tate Specification ofLetters Patent. Patented Mar, 3()J 1920, Application led October 19, 1918. Serial No. 258,880.

at the top, that will engage the marginal portion 14 of the cap member 10, see Fig.

6, and which ange may be given a slightly downward bend as shown. One end of the band 11 is provided with an extension at the intermediate portionl in the form of a tongue 17, that will lap the other end of the band, but does not have any interlocking engagement therewith.

This cap is designed particularly for closure of a receptacle or jar having aflange a short distance below the top, cially adapted for use with the receptacle illustrated in Figs. 5, 6 and 7. This comprises a sheet metal body 7 having a flange formed by bending'outwardly'at 18; then upwardly as at 19, and then inwardly as at 25, Awhereby is produced a langein whichv the lower wall extends transverse to the body to form a sealing shoulder, see Fig. 5. This receptacle also has the upper edge bent outwardly to form a rounded top or bead as at 20, and which does not project out- 'wardly as far as flange 21, just described.

and is espe-- the top member, whereby the ring or band l .11 will project downwardly in contact with v the flange 21 of the receptacle, and its lower edge will project below this ange 21, as shown in Fig. 6. By the application of downwardl pressure on top of the band and cap, these members will move downwardly and compress the gasket 15 between the bead 20 and the adjacent portion of the cap, see Fig. 7. The ange 1 3 of the cap will pass downward by the bead .20, but will not reach the flange 21 of the receptacle. This downward movement will cause the lower edge of the band 11 t'o project somewhat farther below the flange 21, and thereupon lateral pressure isy inserted inwardly on the projecting edge of the band v11, to bend it to extend transversely inward to engage the lower wall 18ofthe` ilange 21, as shown in Figs. 1 and 7. This will securely retain the band member in this position, and it will secure the` cap and gasket 'in the desired sealing position. Y.

As shown in Fig. 1 the tongue 17 of the band 11 projects in engagement with the outer wall of the other end of the band, and does not interfere with the upper and lower flange portions Vof the band. No locking means is needed as the flange portion of the band extends practically throughout thev periphery of the flange 21. vTo remove the closure it is only necessary for the user to grasp the tongue 17 and pull it outwardly, when the band will gradually yield throughout its length and will be removed from the cap and receptacle. This-will leave the cap free to be lifted oli of the vessel.

' other form of receptacle, and the closure is applied, and pressed downwardly, and the pro]eetinglower edge of the band is bent inwardly to engage the flange, as Vwith thel other form of receptacle.

The receptacle show n in Figs. 5,'6 and! 7 isjnot claimed herein but forms subject matter of vanother application iled by my-y self, Ser. No. 258,878.

What. I yclaim is The combination of a receptacle having its upper edge'rolled outwardly to form a inside ofthe outer wall of. the said shoulder portion, a gasket located in the arch portion of the disk member to be compressed thereby against said bead, and a ring member adapted to pass down around the said flange portion of the disk member and around the shoulder member and provided with an inwardly extending flange at the top arranged to engage the arch portion of the disk member, said ring member extending down below said shoulder portion to be bent inwardl around the shoulder portion to retain t e gasket compressed between the disk member and the said bead of the receptacle.
